Diễn đàn hỗ trợ Firefox

Hello Mozilla Support Team,

I am testing my website in the Firefox browser and noticed some issues with loading speed and mobile responsiveness. The website works properly in other browsers, but in Firefox, some sections are not displaying correctly.

I already tried:

Clearing browser cache Updating Firefox Disabling extensions

Could anyone guide me on how to fix Firefox compatibility issues for websites?

Thank you for your support.

Suddenly to use Passwords list on Firefox Windows is demanding I sign into Windows, where previously I used the special "master" password I use only on Firefox. I want to disable this intrusion.

Recently I formatted my pc and after reinstalling windows I immediately downloaded Firefox and synced my profile.

For some reason, videos on some (most websites) are not working at all. They just dont play, and these are websites that I used just last week on Firefox, and that I've tested on other browsers and work just fine. I've tried troubleshooting mode, new profile, deleting cache, etc, and nothing has worked. On some websites, I dont even see the player, its just blank, and in others I see the player but no playback (doesnt even seem to buffer).

YouTube works just fine strangely enough.

I do NOT want to use ANY VPN services. Since you introduced this, or rather, forced it on me, my browsing experience has been terrible. How do I turn off VPN? There is no VPN icon on my topolbar despite what your instructions say.

Up until today (3/26) , accessing CompuServe (AOL) mail was not an issue. Now , getting to the site is OK , but when it attempts to access the mail , I get:

Firefox Can’t Open This Page

To protect your security, compuserve.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

What changed overnight? After getting the message , if I click on Mail , it works just fine. There is also a similar message when closing the page , but not every time.

Any clues?

There are some articles that are biased with some real misinformation. One person has an experience and the author is purported to be an expert just because they have some degree with little or no relevance to real world people, just some niche group who would like to be considered mainstream. As much as I love the start page with some interesting articles, it seems most days lately, theories put forth as facts are out of touch with mainstream America.

The page pops up for a second first, then this happens. They worked yesterday. It happens the same in safe mode. opera works for those sites. Firefox hasn't changed. I log firefox's output, find no errors reported. I did upgrade a few packages yesterday: fontconfig, haveged, qt5, nodejs, which .

When I start VPN, it brings me to a page to choose a subscription, but I have a yearly subscription paid in November 2025. Then my Mozilla account says I am logged on but when I click on the application icon I get a circular icon in the window with a cancel button underneath it. See attachment.

I am having problems with logging into the VPN app. I paid a one year renewal in November 2025 and have had access to the app for both logins that use this computer. It is an Apple M1 Macbook Air. On Wednesday, when I tried to connect, it sent me to a page to select a plan for payment.

Then when I tried to sign in again, it gave me the spinning circle shown in the attachment. It has now been a couple of days where I have not been able to use the app.

I do have access to the built-in VPN for one of my logins, but not for the other one. I have gotten replies from general support that told me to try the special support for VPN.

Mozilla Firefox desktop : As at evening of 22nd May 2026, UK time, Firefox will not interface to Aol email. Gives " We can’t connect to the server at mail.aol.com ". Connection was fine earlier today, & as I know of no Mozilla changes, suspect this is a change at the AOL end. no longer permitting access to Firefox.  ?? Other browsers do connect, hence not an AOL outage.

Whenever I am moving my curser (pointer) on my track-pad a pop-up window appears defining the word I stopped on. As I click on a link, the pop-up appears before the link is opened. Very annoying, never experienced this before, I have been using Firefox for years.

Hey everyone!

I just noticed that post FF's 150 update, I can no longer drag and drop folders into my DSM window. This has been a non issue for over 6 years and all of a sudden, poof. I did find that you can still to this on Safari, but long term, Mozilla and Synology need to address this. There's already a post on the Synology fourms about it and I've emailed their Support Team to see what they have to day. Posting this here in case anyone has found a workaround in the Config settings pane.

Thanks! --Brian

Prior to the latest release I could easily log into the site https://fun.chicagotribune.com/game/tca-jumble-daily. I can login in but once at the player page I must enter command shift R to reload the page afresh. The response is very slow relative to the previous edition of Firefox. There are other examples I could site with similarly odd behavious. Just today I tried to make a reservation with resy. I got a total runaround to my entries. I eventually gave up and used Safari and everthing proceeded as expected and I made my reservation.

FireFox Browser messed up my Internet Download Manager and made it impossible to copy and paste from MS WORD to my emails. Once I uninstalled IDM, I was able to copy and paste. I could not even open a picture in another TAB as before. So the browser was updated and messed everything up. I tried the MS EDGE browser, and it functioned like FireFox browser use to as of today.

I frequently need to access logs in HTML format from a particular application. I find Firefox more comfortable for this, so I visit the parent path directly in the browser. However, the default sort order is by name; since these are logs, it's more useful for me to list them by last modified time. Is it possible to make this sort order the default when visiting file:// paths?

I've attached an image of what I typically visit for completeness.

Thanks.
